A spur gear H5 is fastened to the shaft II5 of v the roller H4. Rollers III, III and II! are also positioned between the extensions 31 and 39 and 'their shafts are journaled thereto. Reduction gears I20, I2I and I22, which are journaled on studs extending from the extension 31 are interposed between the gears H3 and IIG. A warp beam I23 and a pair of squeezing rollers I24 and I25 are positioned between the extensions 35 and 38, and their shafts are journaled thereto. A tank not shown, for drippings may be "located below the-squeezing rollers I24 and I25. Guide rollers I25 and I21 are also positioned beshaft I36. A

' supplemental inlet openings I56 Y electric switch I16 coacts between and the terminal I. with the over the roller I21,

in the housing I45.

v simultaneously and fastened to the extensions 36 and 36. Guide rollers I29a and I2") are Journaled to end'walls of the tanks I29. The warp of textile I36 oper-- ated upon extends from the beam I23, and is led then over the adjacent roller 129a under the roller I26!) and next over the other roller I29a of the tank I 26 where it is impregnated with the sizing fluid. The warp then extends over the guide roller I26 and under the guide roller I 26 to the outer curved bearing sur- .faces 54 of the supporting bars 53 of the drum 4I.

Attention is called to the fact that the portion I 36a of the warp I36, between the guide roller I26 and the drum 4I runs in a straight line tangent to said drum 4| for the eiiicient drying of the warp as it enters the drying chamber 26,

before being'bent by contacting with the drums in said drying chamber. The warp I36 next contacts with the drums M, 42, 43, 44, 45, 46 and 41 in a circuitous route through the drying chamber 26.

The warp I36 leaves the drying chamber 26 through the opening 35, passes over the guide rollers H1 and H6 and under the roller H9, and is finally wound on the roller II4 as a sized beam of warp.

In the heating chamber 21 is indicated a heater I35 with the valve chamber I16. A valve I31 in the chamber I36 extends from a shaft I36. A handle I39 and a pointer I46 extend from the scale I on the wall of the valve chhmber I36 is indicated for the pointer I46. A housing I45 with openings I46 extends from the valve chamber I36. A fan not shown is journaled An electric motor I56 is indicated in the heating chamber 21. The arma- -ture shaft of the latter motor is connected to the shaft of the fan in the housing I45. A discharge nozzle I52 extends from the housing I45 and at its ends are indicated the cross-wise discharge outlets I53. A circulating conduit I55 having the leads from the opening 32 in thetop wall 22 to the heater I35 on the outside of the drying chamber 26.

Referring to Fig. 5 which shows a wiring diagram, the "electric motors are again shown at I and I56. Wires I66 and I 6I connect said electric motors. A source of electric current is shown at I65. Wires I66 and I61 extend from the source of electric current I65. The wire I66 connects the wire I66 and the source of electric current I65. The wire I61 is shown with the terminal I66. Awire I65 extendsfromthewire "I. An

scribed both the electric motors I66 and I66 are the switch I16.

To operate the drying apparatus the warp I36 is strung in operative position in a circuitous path about the drums 4| to 41 as indicated in Fig. 1 of the drawing. The switch I16 is closed and thereby both the electric motors I65 and I56 are energized and rotate.

with the rotation of the motor III the roller 4' turns, whereby the warp I36 moves through 2,168,466 1 tween the extensions 36 and 36 and their shafts the. drying chamber 26 in the circuitous route indicated by the arrows A, to insure a great length of the warp under the influence of the heat in the heating chamber 26. As already called attention to a substantial length of the warp indicated at I36a is heated before becoming curved from contacting with the drums. The warp I 36 is drawn from the warp beam I23 and wound on the roller-H4. When the warp I36 contacts with the rollers H to 41 in the drying chamber 26 it bears on the outer curved bearing surfaces 54 of the bearing bars 53, whereby kinks in the warp are avoided. At the same time the electric motor. I66 through the belts H2, 96 and I II and the belts connecting the pulleys of the shafts 56 rotate the same, and thereby the fans in the drums are turned. a

The electric motor I56 with its coacting appurtenances turns the fan in the housing I45, whereby air is drawn from the heating chamber 21 and discharged into the drying chamber 26. Simultaneously the air which has contacted with the warp I36 in the drying chamber 26, is drawn therefrom through the conduit I55 and flows through the heater I35 where it is heated. From the heater the air flows through the valve chamber I36, and the amount and velocity of flow of the air is controlled by the valve I31. The air from the h'eater I35 then flows through the housing through the circulating conduit I55, fresh air enters the same through its supplemental inlet openings I56. At the same time a portion of the moist air in the drying chamber 26 is drawn therefrom by means of the exhaust fan 96. The air enters the fan 66 through its inlet conduit 9i andis discharged therefrom through its outlet conduit 92. By this means the air in the drying chamber 26 is prevented from being over saturated with moisture. The fan 96 is driven by the electric motor I 65, through the interposed belting described therefor.

Various modifications may be made in the invention and the present exempliflcation is to be taken as illustrative and not limitative thereof.

Having described my invention I claim:

In a drying apparatus of'the character described the combination of a housing-comprising a heating chamber and a drying chamber, means .in the drying chamber to movably support a warp chamber to rotate the said fan, a discharge nozzle extending from the housing of the fan into the drying chamber, an exhaust fan for the drying chamber and means to rotatevthe exhaust fan.
